What is a potential risk of an unstable fuel supply?

An unstable fuel supply can lead to a flickering or unstable flame because the burner relies on a consistent and steady flow of fuel to maintain a proper combustion process. When the fuel supply is inconsistent, it disrupts the mixture of air and fuel, which can result in erratic combustion. This instability can cause variations in the flame, leading to fluctuations in heat output and efficiency. Proper combustion requires a stable fuel supply for optimal performance and safety. If the flame is unstable, it is often an indication of issues that could potentially lead to more severe problems, such as incomplete combustion, increased emissions, or even safety hazards like the risk of fire or explosion.
